المدربA trade condition (or sale condition) is a code attached to a trade report that says what kind of trade it was and how it may be used: a regular trade; an opening or closing auction print; an odd lot; a trade reported late or out of sequence; a trade at an average or derived price; a correction or a cancellation of an earlier report. The consolidated tapes and each exchange define which conditions update the last price, the high and low, and the volume.
